Hey there,
I have Mythemeshop extended membership. It says theme can be used on client’s site and is GPL licensed and does not require any key to get activated.
I dont have money to donate, but I can share my themes here :)
Can I?

Saksham, very kind of you to offer your themes. Unfortunately you cannot share them with us, because we need to ensure that they are completely untouched (nothing added or removed) and coming directly from the developers we need to download them ourselves and cannot redistribute them if they passed through someone else’s hands before.
